First and the foremost, you need to start prioritizing things in your life. You should try to list down your daily tasks, separating the important ones from the unimportant ones. This way, you will be able to work on the most important things in your life and you will not waste time on the less important ones.
Secondly, start making daily schedules. You need to keep a planner with you at all times. You need to list down the tasks on a daily basis so that you have everything on a piece of paper for the day. This way, you will not deviate from the tasks.
You need to reduce distractions as much possible. Some common distractions include playing mini games on cell phones, listening to music and the like. When you think you are bored of working, take a calculated break and get back to work. Once you are back, do not let anything distract you.
Keep in mind that all responsible people eat well, sleep on time and are very organised. This is what gives them the energy and power to focus on the chores. Make sure you are sleeping on time and eating well.
Be prepared for any mishaps that might occur along the way. For instance, a minor injury or a health issue can cause turbulence in your organised life. For most responsible people, there are no distractions. But, those who are not focused enough are distracted by such mishaps and they never find their way back.
Try to avoid forgetting things. It is a common trait among irresponsible people that they forget things easily. Make sure you make a note of every major thing that happens so that you know when to do what.
